BYM/ /W A TTOR Y- 1., This invention relates to electricalconductors, The principal object of the invention is "the provision of a non-:abrasive clamp for ;flexible electrical conductors. l 6- 3:

A further object of the invention is the provision of clamping, means, 017 3, flexible electrical conductor including means for frictionally engaging the same.

The non-abrasive clamp shown and described herein has been devised to form a simple and emcient device for establishing a supporting connection to a flexible electrical conductor such as a cable. The non-abrasive clamp secures the flexible conductor or cable by providing a torturous channel through which the conductor may be easily initially positioned and subsequently moved and which will by frictional engagement with the flexible electrical connneotor, secure the said connector at any desired point thereon.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in, the accompanying drawing, wherein- Figure 1 is a side elevation of the non-abrasive clamp.

Figure 2 is a top plan View of the non-abrasive clamp.

Figure 3 is a side elevation on a reduced scale of the non-abrasive clamp and illustrates a section of flexible electrical conductor in clamped position therein.

By referring to the drawings and Figures 1 and 2 in particular, it will be seen that the nonabrasive clamp consists of a plurality of tubular members III], II and I2 connected with one another by means of curved channels it and ill, the curved channel l3 connecting the bottom of the tubular body with the bottom of the tubular body member I l. The curved channel M connects the top of the tubular body member H with the top of the tubular body member l2. The composit tubular and channel member may be obviously formed from a section of tubular material such as pipe by cutting away two sections thereof inwardly from the ends thereof and spaced with respect to each other, the sections cut away being one on the bottom and one on ELECTRICAL CONDUCTORS' Andre San un s wn 01 1a Application bctober 1, 194" Claims.

clamp for V connecting section i f materiahaare'formed in 1 izsh'apes ztheidevice. illus' tratdf: in" Figure therebyiunformedj and .iin order: I that i this; device maygibe; conveniently mounted to a supporting elementsuch asflcfor'exe am'pla aztsti'iuctural portion aifiaa'noele'ctromagnet or a structural portion of a crane, a separate and distinct bracket I5 is afiixed to the plurality of body members 10, H and I2, as by welding the bracket l5 thereto, as indicated by the numeral 20. The bracket I5 is provided with a pair of openings 16 and lBA by means of which it may be bolted to a supporting structure.

In Figures 1 and 2 the clamp is illustrated prior to the insertion of a flexible electrical conductor therethrough, and it will be observed that dotted lines 2| in Figure 1 indicate the areas in which a flexible electrical conductor may be positioned by first passing the same downwardly through the body member [0, curving it upwardly and around the channel 13 so that it lies therein, passing it upwardly through the body member ll, curving it downwardly and around the channel member l4 so that it lies therein, and passing it finally downwardly through the body member l2. The end emerging may then be electrically connected with the article to be energized and effectively support the electrical conductor by the frictional engagement of the conductor with the tubular body members ill, II and I2, and particularly the curved channels l3 and M which are in oppositely disposed relation.

In Figure 2 of the drawings, a top plan view of the non-abrasive clamp is shown and the interconnection of the curved channels l3 and M with the body members It], II and I2 may be seen.

By referring now to Figure 3 of the drawings a side elevation on a reduced scale in comparison with Figures 1 and 2 may be seen, and it will be observed that a flexible electrical conductor I1 is shown in position in the non-abrasive clamp, the flexible electrical conductor including an electrical conductor l8 and a section of insulating material I 9. It will be observed that the conductor has been passed through the tubular body member l0 around the curved channel member l3, through the body member I I, around the curved channel member l4 and through the body member l2. In such position therein, either end of the conductor may be used as the connecting end depending upon the location of the supporting structure to which the supporting bracket I5 is afiixed.

the; topiplane 1o It will thus be seen that a simple and efiicient non-abrasive clamp for an electrical conductor has been disclosed which possesses the unique advantages of being simply and economically formed and capable in operation of holding a conductor through simple frictional engagement with the same thereby making it possible to support one end of an electrical conductor at a considerable distance from the other Without clamping and distorting the electrical conductor or bending it sharply or in any way contributing to the destruction of the insulation or electrical conductor portion thereof.

Having thus described my invention, what I claim is:

1. A non-abrasive clamp for flexible electrical conductors including at least three tubular body members connected by at least two curved channels, at least one of the curved channels connecting the bottom portions of two of the said tubular body members and at least one of the curved channels connecting two of the body members at their top sections, the said tubular body members and curved channels forming a partially enclosed channel including a pair of oppositely disposed reversed curves.

2. A non-abrasive clamp for a flexible elec- 4 trical conductor including at least three tubular body members connected by at least two curved channels, at least one of the curved channels connecting the bottom portions of two of the said tubular body members and at least one of the curved channels connecting two of the bod members at their top sections, the said tubular body members and curved channels forming a partially enclosed channel including a pair of oppositely disposed reversed curves, and a bracket formed thereon for attaching the said clamp to a supporting structure.
